OSG's Threading Tap is a metric A-Spiral Flute tool engineered for reliable blind-hole threading. Designed for professional machinists and fabricators, it delivers precise threads in deep holes with durable, high- performance construction.

• Size / Thread: M20 x 2.5 metric threading to suit common powertrain, automotive, and general machine components.
• Material: Powder metal body offering excellent strength and wear resistance for repeated tapping work.
• Coating: TiCN coating increases surface hardness and reduces friction, helping the tool withstand high-speed, demanding operations.
• Flute Design: A-Spiral flute with optimized chip evacuation to minimize clogging and reduce the risk of tap breakage in blind holes.
• Form: Form E provides an extended flute length for deeper blind-hole tapping without compromising core strength.
• Hand: Right-hand thread standard for most metric applications and assemblies.
• Application: Specifically suited for blind holes, ensuring consistent thread quality in recessed or inaccessible portions of a component.
• Standards: DIN376-compliant sizing to support precise, repeatable results across compatible tooling systems.

This tap is built to empower precision work in automotive, aerospace, and general machining scenarios where blind-hole threads must be strong, accurate, and reliable. The combination of powder-metal durability, TiCN wear resistance, and an extended Form E flute delivers steady performance, fewer reworks, and longer tool life—especially when tapping deep features or working in hard metals. Ideal for operators seeking a robust, high-precision solution that maintains thread integrity under high-speed conditions.
